ARNOLD J. VEST, OF ABERDEEN, \VASHINGTON TERRITORY.

INDICATOR FOR SAW-MILL SET-WORKS.

SPECIFICATION forming part. of Letters Patent No. 325,295, dated September 1, 1885.

Application filed March 23, 1885. (No model.)

To ail whom it may concern:

Be it known that I, ARNOLD J. \Vnsr, a citizen of the United States, residing at Aber' deen, in the county of Ohehalis and Territory of Washington, have invented a new and use ful Improvement in Indicators, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in indicators for saw-mills; and it consists in the peculiar construction and combination of parts, that will be more fully set forth hereinafter.

In the accompanying drawings, Figure 1 is a perspective view of an indicator embodying my invention. Fig. 2 is a top plan View of the same.

A represents a way in which the head-block B travels back and forth. Projecting from one side of the way, at the rear end thereof, is an indicator or hand, G. A shaft, D, is journaled in rear of the way A, and to this shaft is fixed a drum, E. Around the shaft D, on one side of the drum, is wrapped a spring, F, which has one end fixed to the drum and its opposite end fixed as atf. To the periphery cfthe drum is secured the rear end of a band, G, the front end of which band is secured to a lug, b, that projects from one side of the headblock. The indicater 0 extends across the upper face of the band. This band is provided on its upper face with a graduated scale, formed in columns that run parallel to the length of the band. The column to the left is divided into inches. To the right of the inch-column is a column that is graduated to indicate inch-boards, then a column graduated to indicate two-inch boards, and so on to indi cate any desired thickness.

As the head-block is moved forward the band uncoils from the drum, and as the headblock is moved rcarwardly the spring F rotates the drum and winds the band upon it. As the band moves under the stationary hand the operator can see at a glance the number of inches from the standard to the saw, and can tell how many boards of a given thickness the piece of timber he is sawing will make.

If it is desired to saw inch-boards, the operator sets the headblock up for the first slab until the hand comes even with the end of the column indicating inch-boards.

This device will also indicate where to set the headblock for the first slab when it is desired to saw inchboards, after having previously sawed boards of greater thickness, in order to make the slabs come out even, and thus avoid waste.

An indicator thus constructed is cheap and simple, and is thoroughly reliable and efficient in operation.

Having thus described my invention, I claim- 1. The combination of the head-block, the stationary indicator-hand secured to the way in which the head-block travels, and the graduated band that moves back and forth with the head-block, substantially as described.

2. The combination of the head-block, the stationary indicator-hand, the graduated band connected to the movable head-block, the drum to which the rear end of the band is secured, and the spring for turning the drum and winding the band when the head-block is retracted, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ARNOLD J. XVEST.
